Overview
The Glutamate Metabotropic Receptor 1 (mGluR1 or GRM1) is a member of the metabotropic glutamate receptor family, which belongs to the class C G-protein coupled receptor superfamily. GRM1 plays crucial roles in synaptic transmission, plasticity, and neuronal excitability throughout the central nervous system. It is particularly important in cerebellar function, where it mediates parallel fiber-Purkinje cell synapse plasticity, and in cortical circuits involved in learning and memory.
Structure
GRM1 has a distinctive class C GPCR architecture:

Overview
The Glutamate Metabotropic Receptor 1 (mGluR1 or GRM1) is a member of the metabotropic glutamate receptor family, which belongs to the class C G-protein coupled receptor superfamily. GRM1 plays crucial roles in synaptic transmission, plasticity, and neuronal excitability throughout the central nervous system.

Structure
GRM1 has a distinctive class C GPCR architecture:
Extracellular Domain
Venus flytrap domain (VFT): Binds glutamate and other agonists
Cysteine-rich domain (CRD): Links VFT to transmembrane domain
Dimerization interface: Forms functional homodimers or heterodimers with GRM5
The study of Grm1 Protein has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
